Faceit lowers my sens

I have the viper v3 pro and haven't played faceit in 2 months for context. When playing cs2 normally my sensitivity is completely fine and the usual however when I try to play Faceit and turn on their anti cheat software it drastically lowers my sensitivity. I've tried to change my sens in game then change it back to no avail. Is there a solution to this? The only time it sometimes works is when I reinstall synapse however reinstalling the software every time i want to play faceit is annoying.
